sh-elf vs profiling

> Is your gcc configured with --with-newlib --with-headers?

$TOP/gcc/gcc/configure --prefix=$PREFIX --target=$TARGET \
  --enable-languages=c,c++ --with-newlib --with-mpfr=/usr/local

I do a two-phase build.  I build gcc (and let it fail for libgcc) to
get xgcc/cc1, then build and install newlib, then go back and build
gcc.

But it fails even in one of our recent combined-tree builds too.
